To all whom it may concern:

Beit known that I, Geoncn L. Dinox, a citizen of the United States,residing iit Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Im rovement-s inMount- Heavy Doors of Vfes and Vaults, of w ich the following is aspecification.

This invention relates to mountings for heavy doors of safes, vaults orthe like.

The users of large safes und vaults have heretofore had a great deal oftrouble with the heavy doors. This t-rouble hns been due to the factthat, when the hinges of u door of this type wear slightly, the centerof the door sags to such an extent that the door in some instances hasbeen closed with diliculty and in other instances cannot be closedwithout the assistance of experienced help with appliances. To overcomethis dicult-y a pressure system has been employed to force the door toits sent but this system while effective when the door does not sa toofar, is of no use when the lower ed: o the door drops below the doorsent.

an application .vously filed b me, I disclose n. construction in whichthe oor is sustained in such n manner that the door may be readilybrought into the seating pcsition by or preferably depressing the dooreither from a position into which 1thas settled from some yielding inits mounting or from a slightly raised position, any snitsble pressuresystem be' employed, if desited, in connection with moun The presentinvention has for an oblect to accomplish this same result by a. new anduseful means in which the door is movalf' supported on its mounting andcounter lo ed in such a. way as to facilitate raising it to its sontblthc application of n comparatively very eine. force, or dep it to itsseatinposition without inconvenience.

out in inventionl em loy c lever system by weight of thg door issustsined either in whole or .in pci-t upon its mountings und acounter-loading menus, which needy, quite, or doorliy 4thro invention befully upon reference to .the dreiv- Aniodihied ein odiment of m overbalances the the lever system in we' t of thodoor..

in which fin a justable spring constitutes the counterload whichoperates through the medium of the lever sistem.

Referring to all of tigures 1 represents the vestibule, of a lire andburglar-proof vault und 2 the heavy door fitted to the doorway in thevestibule ierably by the well known type of groun joint.

The counterloading means is such that acting through the long arms oflevers 9, it hns an elevating equal to or v ing shghtly from the ondposed by the oor acting through the short arms of the levers, so thatthe door can be readil centered, notwithstanding it may be slight y outof center with the doorway in conse accuracy or settling or weer ing;that to sa r the counterloa effect is lylessthanthe load imposed ythe-doorI or e uol to sudload or slightlyin excess theroo it willreqfiiire npah-M-tc :f ...s m

Theweight may be conveniently mounted u n a hollow sleeve 14 and throughsai sleeve connected wit-h the levels by means of wrist bearings l atthe ends of said sleeves.

According` to the form shown in Fig. 3 the connterloading means is aweight 1 1 l held in f intermediate position on the pintle 4 by means ofs rings 16 which are given a deinite set.- the door should hecomeo' eenc terI the necessary force may be applied to it 2o in either directiont-o compress one of t-he springs and rmitthe door to center- Accordingto the form shown in Fig. 4, the counterloa consists of a spring 17adapted to exert premura against the upper wristbearing which serves asa shoulder, and

transmits it through the sleeve 14 to the lower lever. By means of a nut18, the pressure of a spring 1T may be adjusted so that it; willoverbalance the weight of the door, thus 1 a slight depression of thedoor to seatit, or the tension of the slpering may be such that it willonly sustain t door at or 2 below its center but with sucient tendencyto expend to rform the main work in rais g the door to its seatingposition. i sm ns claims covering the broad idea of thisinvention[)lliia-ve been in my co nding up cation, ria o. 393,181,cliiertain broad claims which could 4o have been made upon thesubjeetsmatter of the present application, have not been embodiedtherein Having thus described my invention the following is what I claimas new therein and desire to secure Letters Patents- 1. In combinationwith a door, a lever system which sustains the entire 'weight of the ddoor; and a. oounterload acting u said lever system in opposition to theweight of the door. i

2. In combination with s mounting for heavy doors, upon which the doorhas relative vertical movement, a lever system thro h which the entireweight of the door 56 may d on its mounting, and a eounteriosd ac throthe lever system in to of the door.

3. with the mounting for heavy doors, s lever mounted on said 6omounting, which e entire weight of the door may e sustained vertically,and s said door and tendi l bination of o suppe counteru'eiglit actingon said Ioni-system in opposition to the weight of the door.

4. In combination with u safe or vault having a doorway and a door; themounti for the door by which it is carried to and rom the doorway; alever-system fulcrumed on the mounting and sustaining on one side ol"the fulci'um, the weight of the door; and a counterload acting u n thelever-s tem on j the opposite side ot t e tulerum en in opposition tothe weight of the door.

5.
